A money order is a paper payment, like a check. It is considered safer than a check because it's prepaid, so there's no risk of a money order "bouncing."You need to take your money out of Chime at the ATM and then buy a money order at 711 or maybe a bank will do a cashier's check for you for a fee. Money orders are a safe alternative to cash or checks. Find out how much they cost, when you need one, where to buy it and how to cash it. Forms of payment accepted on The Postal Store®. VISA®; MasterCard®; Discover®; American Express™. While you can technically buy a money order with a credit card, it's not a good idea. You'll need to do a cash advance to purchase the money order.
